People who are close to him consider him a good person, although he admits that the "good" actions he has taken were only done because he believed they would disrupt his peaceful school life if he didn't do them. His special ability is to see and control ghosts, a skill that has caused him many problems in his life. His favorite pastime is doing nothing and sleeping.

She is a 15-year-old ghost girl, but she has the appearance of a 10-year-old because she died at that age. She hates it when Saik treats her like a little girl, but her childish personality and behavior don't help Saik see her as a mature girl. Her childish personality and behavior make Saik consider her his little younger sister. Her favorite hobbies are watching TV, playing video games with Saik, eating sweets, and spying on people.
